Cheap powerful graphics cards for all

Photonics.

We are so close it's killing me.

Fusion power or cures for diseases.

Fusion power, should it work, would solve a lot of problems. Environmentally, in particular, but if we could get a decent distribution of reactors around the planet we’d alleviate food problems, water problems, and a whole bunch of suffering of one kind or another. Cheap power would help a lot.

Otherwise, anything to help cure diseases. Genetic, auto-immune, cancers, misfortune, whatever. Alleviate more suffering, let people live and work again.

Fusion

Tech Debt. So many of these companies investing in AI are doing so at the expense of out dated, broken shit that AI will never address.

AI to run companies in sustainably profitable ways that benefits their workers instead of rich greedy sociopaths.

Easily the education system at least here in America cuz it's dog shit. I honestly think there should be another year for high school just one more because kids are coming out of school completely unprepared for anything and I don't just mean common sense I mean jobs entry level jobs kids can't do because school didn't teach them the basics

Edit: I sat down now so I want to elaborate.

I really think schools should focus more on life skills cooking, home improvement, changing your tire and brakes. Everyday stuff you'll run into but a lot of people don't know how to do. Just doing it once or twice gives people the confidence that they can do it and can maybe do more. That's my two cents, that I don't have

Cryptocurrency.

Kidding! Sorry, I couldn't help myself. I'm sure that will ruffle someone's feathers for a fraction of a second.

Does vegan based meat/milk alternatives count as a technology sector? The moment we figure out a way to actually seriously imitate high quality steaks and 2% cow milk with it being indistinguishable and half the price I think that will hurt factory farming which is a bit of a domino effect that would lead to less co2 and methane produced, less agricultural effort wasted on feeding animals, that kind of thing.

Give money to the artists the AI stole art fr.... I mean sex robots

Methods of updating energy infrastructure to accelerate the switch to renewable energy?

I would make Star Citizen AAAAAAAA... game.

Probably thinking too small, but if I were rich, I'd give a bunch of money to OpenStreetMap.

Thermonuclear reactors

Energy storage. We could already produce all the power we need and more using solar power, the problem is that we can't store it in an efficient energy dense form. The word efficient there is doing some heavy lifting. It needs be comparable or better than our methods today in terms of cost, safety, energy density, climate impact. If we could solve energy storage, it'd change society and technology dramatically.
